Always using it in every tank I have. Never got an issue with Surgeons and activated carbon. Tried and I'm using a few (random) brands as AC.
Just what I'm trying to avoid is tumbling it. The water has to pass through it but not to force the particles rub in each other releasing dust in the water current. Tested and using it in a media reactor and in bags in the sump in a high flow area.
Every single system I have is with activated carbon in it, replacing it every 3-5 months (by this reason I'm overkilling the amount of it), also it helps for the beneficial bacteria as well.
